PURPOSE: A method for converting heavy aromatics and a converted product obtained by the method are provided, to convert the heavy aromatics comprising a C8+ alkyl aromatic compound into benzene, toluene or xylene. CONSTITUTION: The method comprises the steps of providing a reaction region containing a mordenite catalyst; introducing source materials into the reaction region to allow the source materials to be contact with the mordenite catalyst under the selected condition; converting the source materials under the initially selected condition; controlling the reactor condition needed to maintaining the conversion of source materials; and removing the converted product from the reaction region. Preferably the mordenite catalyst is selected from a nickel-containing mordenite catalyst, a palladium-containing mordenite catalyst or a platinum-containing mordenite catalyst. 본 방법은 중방향족, 상세하게 C-C범위의 중방향족을 니켈, 팔라듐 또는 백금-개질 모데나이트 촉매를 함유하는 톨루엔 불균등화 유니트를 사용하는 벤젠, 톨루엔 및 크실렌의 보다 다양한 방향족으로 전환하기 위해 제공된다. 본 방법은 많은 양의 중방향족 화합물이 촉매 활성 또는 촉매 수명에 역효과없이 진행되도록 한다. 이는 일정한 반응 엄격 조건에서 반응기로 중량 알킬방향족 화합물을 도입하고 전환 중에 그러한 조건을 유지하여 달성된다.
